Benefits of technology

[0012]Another object is to provide a blast freezer and storage freezer arrangement and method that is less expensive to build, operate and maintain than conventional blast freezing and storage facilities.

Problems solved by technology

This use of two sets of refrigeration equipment is not only expensive to operate, but is also quite labor intensive for maintenance and repair considerations.

Embodiment Construction

[0019]Referring now to the drawings, the freezer arrangement of the present invention is designated generally at 10, and is shown arranged within an enclosed room 12. Room 12 is divided into three areas, designated generally as the storage area 14 and two blast cells 16 and 18. It should be noted that storage area 14 has a volume that is much larger than the volume of either of blast cells 16 and 18.

[0020]The effective volume of blast cells 16 and 18 is delineated by a low ceiling 20 and 22 extending over the top of each blast cell 16 and 18, respectively. Ceilings 20 and 22 reduce the effective height of blast cells 16 and 18 to less than the height of storage area 14. Slide doors 17 and 19 are installed to further separate the blast cells 16 and 18, so that air flows through the unfrozen food product 50 from the ends open to storage area 14.

[0021]Because blast cells 16 and 18 are identical, only blast cell 16 and its associated evaporator unit 26 will be described in detail herein...

Abstract

A freezer arrangement includes a room having a storage area and a blast cell, with the volume of the storage area being greater than the volume of the blast cell. Frozen food product is positioned in the storage area. A refrigeration unit draws air from the storage area and through the blast cell to rapidly freeze the unfrozen food product. Air from the blast cell is chilled and blown back into the storage area. A method for rapidly freezing unfrozen food product includes providing a room with a large storage area and a smaller blast cell. Unfrozen food product is loaded into the blast cell and a refrigeration unit is operated to draw air from the large storage area, through the blast cell, chill the air, and exhaust the chilled air into the storage area, until the food product in the blast cell is cooled to a predetermined temperature.

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]Applicants claim the benefit of U.S. Provisional Application Ser. No. 60 / 543,173, filed Feb. 10, 2004.STATEMENT AS TO RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT[0002](Not applicable)INCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISC[0003](Not applicable)BACKGROUND OF THE INVENTION[0004](1) Field of the Invention[0005]The present invention relates generally to apparatus for the rapid freezing of food products, and more particularly to an improved method and apparatus for blast freezing and storage of food products.[0006](2) Description of Related Art[0007]Traditionally, freezers and blast freezers in industrial plants have been separated. Freezers consist of refrigeration units having sufficient storage shelves, racks, and / or pallets for holding frozen product and maintaining the frozen product in a frozen condition. Freezers are found in a wide variety of sizes, from the small units formi...
